I am slowly making progress on my full time move to Paris which will include bringing my 12 year old kitty. I've already worked through the paperwork requirements with my vet and my concern now is actually traveling with him. He's 12 years old and always been an indoor kitty in a quiet environment. Within the past few weeks he has made 3 trips to the vet in a carrier and has screamed during the entire 1 mile trip which has me concerned about making a trip from the US to Paris with him in the cabin. The vet advised against sedatives and recommended that I get him use to the carrier. I've thought about shipping him as cargo. Any suggestions, tips etc...
